Vlad [161]
<span>A major difference between the eccrine sweat glands and the appocrine sweat glands is that eccrine glands empty into/onto the skin surface while apocrine glands empty into/onto the hair follicle.
There are two types of sweat gland, eccrine and apocrine. As the eccrine glands empty into the skin surface, they are present all over the body particularly on forehead, palms and feet. That's why we feel more sweat on these parts of the body. while apocrine glands empty into/onto the hair follicles so they are mostly armpits.</span>

just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
